1000 OTS/OTR
« on: February 17, 2016, 04:05:42 pm »
Hi, this is my 850 coupe s1.
I am changing the engine to 1050cc so I need more cooling, I found that MK1 Ford Fiesta radiator will fit nicely in the front.
Can you help me with pictures of the underside of the car, to see the coolingpipes of the water and oil.
I will try to replicate the OTS/OTR cooling system.

Hope some of you can help me, thanks!

I got the car running and it sounds glorious!
it is idling very rough though.
It also went out of breath on higher revs on the road, so I opened the carb (DCD 28/36)to see what was inside.
The first thing I found was that the emulsion tubes had changed place, so the bigger one sat on the smaller side of the carburetor.
When I changed this the car would rev up the range, but still it will not idle and when warm it hesitates when you blip the accelerator.
Also the idle mix screw has no effect, only when bottomed out.(stops the engine)

The jetting is:

Starter air jet 150
Main jets 125/125
Idle jets 50/70
Emulsion tubes 200/220
Chokes are 24

Engine is Abarth 1050 ccm 70 Hp.

Does anyone have an idea if the jetting is way off or in the "ballpark"
Maybe the main jets also should be different sizes...?

Thanks!

Hi!

Thank you!
I got this engine here in Norway finished with reversed rotation.
They are starting to get pricey....:-/
